Product Description

The Model TT-101 PTP / Time Code Synchronized Generator is a low cost high performance unit that provides many features typically found on higher cost units. The TimeTap is able to synchronize to time derived from PTP two-step time packets. When operated in the IRIG mode, time and rates are precisely referenced to the IRIG generating source. In addition to IRIG B, A, G and NASA36 time code outputs, time is available on the USB port.

The Model TT-101 TimeTap is ideal for providing time and rates for applications requiring various time codes utilizing PTP synchronization or time code input. The TimeTap can provide the drive for large format wall and console time displays. This unit is ideal for use with the TTGM-101 for PTP synchronization over a network as well as time code synchronization. Computer synchronization can be accomplished with optional Domain Time II software.

The TimeTap will synchronize to the selected reference to less than 1 microsecond and supply a variety of timing outputs to the user. This unit can provide local or daylight savings time with settable timing offsets. The TimeTap can also be synchronized to a 1PPS input with time set manually.
